Seam3 or CDI equivalent for org.jboss.seam.core.Interpolator

[iphands]

Does Seam3/CDI expose access to a class that I can use for Interpolation?

In Seam2 I was using org.jboss.seam.core.Interpolator.interpolate() to interpolate XML files (read from disk) before transformation and publishing (so that I can xsl:sort on interpolated values).

What the end goal here is to be able to do something like:

public String getLocalizedXml() {
        // String xml = FileUtils.readFileToString(new File("/foo.xml"));
        String xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><foo><bar>#{messages['foo.bar']}</bar></foo>";
        return Interpolator.instance().interpolate(xml);
}

Found an answer here https://issues.jboss.org/browse/SEAMINTL-16

Off to try the beta bits I guess.

I tried to implement the interpolator from Seam2 (http://anonsvn.jboss.org/repos/seam/branches/community/Seam22/src/main/org/jboss/seam/core/Interpolator.java) in my project, but I am having some issues.

public String getTestString() {
     String expression = "#{messages['nav.knowledge.docs']}";
     String value = expressions.evaluateValueExpression(expression, String.class);
     return value;
}

Caused by: java.lang.NullPointerException

Anyone know why? Is this a bug?

The class I am using to test this is almost the same as the exmple http://docs.jboss.org/seam/3/solder/latest/reference/en-US/html/elextensions.html
